It's pretty widely accepted that Hobgoblin, Venom and Carnage are the only 3 villains to rival the Lee/Ditko/Romita classic rogues but, seeing that we are about a quarter century past Carnage's intro the question becomes: who among the new villains introduced since then are worthy of at least consideration as a classic villain?
For me, I can only come up with Morlun, Mr Negative and maybe Fusion (from Jenkin's run) though he hasn't been used since then for some odd reason.
I know that it is a rarity for a 55-year old series to introduce popular new characters this late in the game but what do you guys think? Have there been many/any since Venom and Carnage that are worthy??
